Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to a water-sealed acid tar residue tank. Background Art

[0002] Currently, the spray-type saturator uses ammonium sulfate mother liquor to circulate and spray, washing out ammonia and acid tar residue carried in the coke oven gas. Ammonia reacts with sulfuric acid to form ammonium sulfate, which is then used in the next ammonium sulfate drying process. The acid tar residue in the saturator is discharged into the full flow trough through the inner saturator full flow port and the acid tar discharge port. The acid tar residue in the full flow trough is suspended on the surface of the ammonium sulfate mother liquor. The acid tar residue is then cleaned and moved to the acid tar residue discharge port on one side of the full flow trough to be discharged into the acid tar residue trough. The acid tar residue in the acid tar residue trough has a relatively pungent tail gas (carrying some coal gas). If this tail gas is not sealed, the entire unit will be filled with pungent tail gas, which also poses a potential explosion risk. Utility Model Content

[0003] The purpose of the utility model is to address the defects of the existing technology and provide a water-sealed acid tar residue tank. By water-sealing the acid tar residue tank, the process of discharging the acid tar residue in the full flow tank into the acid tar residue tank and the tail gas generated by the acid tar residue in the tank can be sealed and treated. This part of the tail gas then returns to the full flow tank through the full flow tank acid tar residue discharge pipe. The negative pressure tail gas pipeline connected to the full flow tank sucks the tail gas away and enters the subsequent treatment procedure.

[0004] In order to achieve the above objectives, the following technical solutions are adopted:

[0005] A water-sealed acid tar residue tank comprises an acid tar residue tank, a water-sealed cover, and a wheeled base. The water-sealed cover is connected to the acid tar residue discharge pipe via a flange. The water-sealed cover is placed on the top of the acid tar residue tank and seals the water-sealed cover and the acid tar residue tank with water, allowing exhaust gas in the acid tar residue tank to return to the full-flow tank along the full-flow tank acid tar residue discharge pipe. The acid tar residue tank is placed on the wheeled base.

[0006] Furthermore, the water seal cover includes a water seal cover body, a handle and a flange pipe mouth. The upper end of the water seal cover flange pipe mouth is connected to the flange of the full flow tank acid tar residue discharge pipe, and the lower end is covered on the water seal groove on the upper part of the acid tar residue tank to achieve water sealing effect.

[0007] Furthermore, the acid tar residue tank has a water seal slot on the top for draining water and a water seal cover, and handrails on both sides of the middle.

[0008] Furthermore, the wheeled base includes a base plate, wheels, pressure springs, pull rings and pull rods. There is a pressure spring between the wheels and the base plate, and the wheeled base can be moved by pulling the pull rod.

[0009] Furthermore, the pressure-bearing spring can select a suitable spring force by calculating the medium density.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are:

[0011] (1) In view of the problem that the tail gas in the acid tar slag tank is difficult to be sealed and collected for treatment, the acid tar slag tank is sealed by a water seal cover, so that the tail gas in the acid tar slag tank can be sealed and extracted through the negative pressure tail gas pipeline in the full flow tank for subsequent tail gas treatment process, which meets environmental protection requirements and improves the environmental safety factor.

[0012] (2) With a wheeled base, when the acid tar residue is close to being full or needs to be replaced and moved, it can be moved by the traction rod on the base, which saves time, effort and is convenient.

[0013] (3) The pulley base adopts a pressure spring. By setting the elastic force of the pressure spring, the acid tar slag tank is filled or reaches the pre-set load-bearing value, and the acid tar slag tank is settled as a whole, thereby separating the water seal cover from the water seal slot, making it easier to replace another acid tar slag tank.

[0022] Example 1

[0023] In a typical embodiment of the present invention, Figures 1-6 As shown, a water-sealed acid tar residue tank is proposed.

[0024] like Figure 1 The water-sealed acid tar residue tank shown is used to carry the acid tar residue and seal the tail gas in the acid tar residue tank, which is then extracted through the negative pressure tail gas pipe on the full flow tank for subsequent processing, thereby reducing the pollution of the acid tar residue tank to the ambient air and improving the efficiency of tail gas collection.

[0025] Combine Figure 1 The water-sealed acid tar residue tank includes an acid tar residue tank 1, a water-sealed cover 4 and a wheeled base 7. The acid tar residue tank 1 cooperates with the water-sealed cover 4 to seal the tail gas in the acid tar residue tank 1; as the acid tar residue in the tank is collected, the wheeled base 7 and the acid tar residue tank 1 cooperate with the water-sealed cover 4 to achieve the sedimentation of the acid tar residue tank 1 through the action of gravity, and then the water-sealed acid tar residue tank is replaced by traction of the pull rod 11 of the wheeled base 7, thereby reducing the leakage of tail gas and improving the efficiency of tail gas collection and replacement of the water-sealed acid tar residue tank.

[0026] Specific, combined Figure 1 、 Figure 3 The water seal cover 4 is placed on the top of the acid tar residue tank 1. Initially, the upper end flange 5 of the water seal cover 4 is connected and fixed to the lower end flange of the full flow tank acid tar residue discharge pipe. The lower part of the water seal cover 4 is completely stuck in the water seal slot on the upper part of the acid tar residue tank 1. When the acid tar residue is collected, the tail gas in the acid tar residue tank 1 can be sealed, thereby collecting the tail gas into the full flow tank for subsequent processing.

[0027] The upper flange 5 on the top of the water seal cover 4 is connected to the lower flange of the full flow tank acid tar residue discharge pipe; the flange cover 4 is then fixed in mid-air to achieve a water seal with the water seal slot on the top of the acid tar residue tank 1 below.

[0028] Specifically, such as Figure 5 As shown, for the pulley base 7, the acid tar residue tank 1 is placed on the pulley base 7. After collecting the acid tar residue that is fully flowing in the full flow tank, the pressure spring 9 is compressed by gravity, so that the acid tar residue tank 1 is separated from the water seal cover 4, and the pull rod 11 is connected to the pull ring 10 on the side of the pulley base 7. At this time, the acid tar residue tank 1 is moved by pulling the pull rod 11, and then another acid tar residue tank 1 and the pulley base 7 are replaced, thereby realizing the rapid replacement of the water-sealed acid tar residue tank and greatly reducing the exhaust gas emission when replacing the acid tar residue tank.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
